To all whom it may concern:

Be it known that I, ANATOL .GOLLOS, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois,hareinvented certain new and useful Improvements in Track Apparatus forSignal or Stop Systems, of which the fol lowing is; a specification.

The use of an intermlttent third rail, or

contact rail as it is more commonly called,

in connection with railway signal systems or stop systems, hasheretofore been proposed or adopted. Ordinarily these contact rails orcontact members comprise relatively short sections, usually arrangedadjacent to the end of a block and supplied with a feed wire whereby therailmay be energized, these rails operating in conjunction with contactshoes or contact devices arranged on the car or locomotive. An objectionto the usual arrangement of such contact rails and track circuits asheretofore arranged has been that the contact rail might become torn outentirely, or moved to such an extent that the contact shoes would nottouch the same, without affecting the system so that a warning would begiven of the dis placement of such rail.

The principal object of the present invention is to arrange the wiringof the track system so that the tearing out or displacement of thecontact rail will act upon the track circuits so 'thata proper warningor signal will be given.

I have illustrated my invention in the accompanying drawings in which,

Figure 1 is a diagrammatical view of a track system embodying thisinvention; Fig. 2 is an end view of an undercontact rail showing onemethod of securing a circuit wire thereto; Fig. 3 is a side view of theparts shown in Fig. 2; Fig. is an end view of a contact rail for anoverrunning contact shoe showing the circuit wire attached thereto; andFig. 5 is a side View of the parts shown in Fig. 4.

As indicated in these drawings, 6 represents one of the track railswhich is insulated at the ends of the blocks, and 7 represents the otherrail which is continuous. Each block is provided with a track battery 8which is connected to the rails "6 and 7 by wires 9 and 10 adjacent tothe exit ends is intended for a double track road with,

the trains moving from left to right as in cheated by the arrow, twostations A and B being shown. The apparatus at stationA only, will bedescribed, the corresponding parts at the different stations beinglettered to indicate their location. One of theter- .minals of a relay11 is connected by means of a wire 12 to the rail 7, the other terminal7 is connected by means of a wire 13 to the rail 6 at the right of thestation. One of the switches or contacts 1 E of the relay 11 isconnected by means of a wire 15 to. the

wire 12. Such switches or contacts are commonly designated as the relayarmature which term will be used hereinafter for such contacts. ture isconnected by means of a wire 16" with a battery or other suitable sourceof electricity 17 The other terminal of this battery is connected bymeans of a wire 18 to the second armature of the corresponding The otherterminal of this arma in normal condition the relay ll receives currentfrom the battery 8 adjacent to station B, the circuit being as follows:from battery 8*, wire 9, rail 6, wire 13, relay 11, wire 12*, rail 7,wire 10 back to battery. As long as the circuit remains closed the relay will be energized which will hold its armatures closed so that thecontact rail :21

.B, or if the circuit from the battery to the relay is interrupted, therelay would drop and would open the circuit to the contact rail.

I do not herein claim this general system,

connection between the contact rail 21* and the system except throughthe Wire the contact rail could be torn out or' displaced without in anyWay affecting,thebalance.of

the system, and if a train passed the block Where the rail was torn outor displaced it would receive nowarning. signal or would notbe stopped.In order to overcome this objection l carry the W1re '12? alongside therail in and secure it thereto in any conenient manner so that if therail is torn aivay or displaced itwill break the Wireand thereby openthe circuit from the track battery to the relay 11. If desired, afrangible link or other connectorsuch as indicated at 22 may bearrangedin the wire 12 =so that it Will be broken instead-of the Wire. It willbe seen that: when the relay opens, it will open thecircuits throughboth of its arma tures and will thereby deenergize the contact rail atthe next station to the left. Forinstance, if the relay 11 is opened thecontact rail 21" Will be deenergized on, account of opening the circuitthrough the armature 14%, This Will cause a train approaching from theleft to be stopped: 01: signaled at the next station to the one Wherethe contact rail is torn out or displaced and: the engineer or operatormay then proceed under caution or according toproper train. rules until.the difiiculty is located.

When an under-contact rail, such as indicated at in Figs. and 3 is used,such rail is usually protected by a ooden'box or cover 24s.- In thisinstance, the Wire 12 may be carried along theside of the box and. heldin position by means of a molding 25.

lVith an over-contact rail, such as indicated at 26 in Figs. and 5,blocks 27 may be secured to the eb of therail at intervals and a molding28 attached tothese blocks for receiving the wire 12 It will bereadilyapparent that various methods may be used for securingthe circuit\vireto the contact rail Without departing from the spirit of thisinvention. Furthermore, my improved arrangement may be used with othertrack systems employing contact railsand having suitable track circuits,the presentsystem being merely illustrative of thegen eral arrangement.I
